<p>re: <a href="https://github.com/rust-lang/rust/issues/80810#issuecomment-783794694">https://github.com/rust-lang/rust/issues/80810#issuecomment-783794694</a></p>
<p>If I were to make arch-specific changes to this <code>max_by_val_size</code>, what's the best way to do that?</p>

<p>should I add this to the target spec? or just hard-code arch information somewhere else?</p>

<p>further context: the s390x regression came from <a href="https://github.com/rust-lang/rust/issues/79547">#79547</a>, but I'd like to leave that optimization in place for arches that work with it</p>
